To use this ISR Performance Front Mount Intercooler Kit, first, make sure your vehicle is an S13/14 chassis with a 2JZ engine and stock twins. This kit won't work with 1JZ engines, so double - check before installation. Open the box and take out the 4 intercooler pipes, 1 M spec intercooler core, 6 intercooler couplers, and 12 T - Bolt clamps. Install the intercooler core according to the instructions, then connect the pipes using the couplers and secure them with the T - Bolt clamps. Remember, this product is designed for off - road use only. For maintenance, regularly check the clamps to ensure they're tight and the pipes are free of cracks or damage. If you notice any issues, replace the parts as needed.
